With GNOME 3.6, polkit and networkmanager moving to [extra], ConsoleKit
has now been removed from the repositories. Any package that
previously depended on it now relies on systemd-logind instead. That
means that the system must be booted with systemd to be fully
functional.
In addition to GNOME, both KDE and XFCE are also affected by this change.

Thanks for your time, Wonderwoofy & brain0. Ultimately I think I was confused and misled by the news item's title using the name 'logind' instead of 'systemd-logind' or just 'systemd'. I thought I was dealing with something that was distinct from, yet somewhat dependent on, systemd.
